Cinema Surround Loudspeaker Specification Sheets
Developed specifically for the unique requirements of 
professional motion picture playback, QSC extends its 
commitment to the cinema market with the introduction 
of the SR-110B Cinema Surround Loudspeaker. As a 
member of QSC’s DCS Digital Cinema Speaker Series, 
the  SR-110B  offers  high-power  handling,  excellent 
sensitivity,  and  extended  bass response  in  a  very 
compact enclosure.
The SR-110B Cinema Surround Loudspeaker features 
a high-power, long-throw 10" low-frequency transducer 
coupled  with  a  1"  titanium  diaphragm  compression 
driver. The system’s  plywood enclosure  features a 
15º  down  angle  baffle  and  Array  Optimized  Tuning 
(AOT) for optimum frequency response. The 200 watt 
continuous  power  rating  and  sophisticated  crossover 
provides absolute reliability.
The compact black enclosure with black grille blends 
into  any  theatre  decor.  A new  QuickMount bracket 
design allows for fast, easy and secure installation. The 
loudspeaker  half  of  the  bracket  comes  pre-installed 
on  each  SR-110B.  The  QuickMount  wall  bracket 
is  purchased  separately to  allow  shipment  to  the 
job  site  ahead  of  the  loudspeakers.  A  traditional  
U-bracket is  also  available in  lieu  of the QuickMount 
bracket system.
